With thev foregoingandxother object-s in view, I havedevsed the device,tWO arrangements 0f whth,are vshown in the accom- 4'panying drawing,similar reference` char- Macters being employed throughout the variousfigures to indicate corresponding. elements.

yItis, however, preferred to operatethe roll by power andvprovidemechanical means associated therewith to present the skin with the`leeceto the, surface of theroll. I have shown `in Fig. lsomewhatdiagrammatically an arrangement ofdevices for this purpose.

`In'this figure, 10 is the work roll which may be rotated at the properspeedbyany suitable teeth 1l inclined to point in the direction'ofymeans, not shown', the, directionV of rotation s' 'i lbeinglindicatedby the arrow, and the surface 'of this roll is provided with smallinclined y rotation. 'These teeth, as indicated above-,

they may be provided by fastening a shark skin tothe surface of thefrollby any suitable means, such as' cement. The diameter Y may be formed bycutting them onthe surface of a steel roll and then hardening or of theroll should betsuiflcient `so that theH per cloth having fine 'bristlesor bristle-like vwires 13, and this isrotatedso that its surfaceV speed.is greater than that of theV working roll 'and in the. samel direction:so that the teeth 13 will catch the rear endsof the'.

kfleece on the work roll and strip it fromthe vibrating Wires'14, whichmay be vibrated by means of a roll'15 running in a toothedvvvheel 16,the stripped fleece being deposited` on a conveyor belt whichit maybecarried to any desired location.

To secure best results and toprevent in-f jury to the surface of theskin by the Work roll it should beheld tauton suitable vsupport While itis being moved past the surface ofthis roll." In Fig. 1 'is shown apainoi y feedrolls 18-to the'rear of the 'Workioll 10,
